Hey, good article. It definitely brought up some talking points on the security of SegWit which I didn't know about and appreciate. You did however, to me, make it seem like finding this info about issues in SegWit was a fairly difficult task but it took me 5 minutes to parse the Core page here: https://bitcoincore.org/en/2016/10/28/segwit-costs/
In "Avoidance"section, part 4, it talks about these issues plainly.
I agree that we may end up using other coins as a means for faster/ more secure payment and have Bitcoin as a main store of value. Time, of course, will tell.
